Abstract (en)
[origin: EP0229368A2] A process for the preparation of ethylene polymers by continuously introducing the appropriate monomers into a polymerisation system at from 60 to 120 DEG C and at from 5 to 60 bar in the presence of a catalyst, an antistatic and optionally a molecular weight regulator in the gas phase in an agitated loose bed of finely divided polymer.
